<p>Here is an invalid iframe.  It should contain a 404 error message, not any green fallback text.
Note this will only work if this page is fetched via http.</p>
<iframe src="error404.pl" width="70%" height="180">
<span style="color:green">fallback text</span>
</iframe>


<p>Here is an invalid object.  It should be rendered with some green fallback text.</p>
<object data="404error.pl" type="image/x-unsupported" width=100 height=100>
<span style="color:green">fallback text</span>
</object>
